Factory and industrial canteens operate under conditions that would destroy standard commercial kitchen equipment: 24-hour operation across 3 shifts, massive peak loads when shifts change, and often dusty or contaminated ambient air that accelerates filter loading. The Souniny ND Series was originally developed with this exact use case in mind.
| Parameter | Specification |
|---|---|
| Model | Heavy-duty Series / Heavy-duty Series |
| Airflow | 8,000-12,000 m³/h |
| Shift Pattern | 24/7 with 3× daily peak loads |
| Ambient Conditions | Dusty, variable temperature (-10°C to +45°C intake) |
| Pre-filter | Heavy-gauge washable mesh (industrial grade) |
| Control | PLC with shift-based scheduling |
| Durability | 0.8mm aluminum plates, industrial powder coat |
Application Scenarios
- Foxconn electronics factory (Shenzhen): A massive factory campus with 8 canteens serving 80,000+ employees across 3 shifts deployed Heavy-duty Series units with water-spray pre-treatment. Each canteen serves 10,000 meals per shift with peak cooking intensity during the 30-minute shift change windows. The ESP modules are programmed to ramp to full power 15 minutes before each shift change and reduce to idle during off-peak. The system has operated for 3 years with only scheduled maintenance.
- Automotive plant canteen (Germany): A BMW plant in Bavaria with 4 canteens serving 15,000 employees uses Heavy-duty Series units integrated with the factory’s central BMS. The system is linked to the production schedule — ESP modules automatically adjust based on which shifts are active. During the annual 2-week plant shutdown, all modules run a deep-clean cycle and receive preventive maintenance.
- Textile factory canteen (Bangladesh): A garment factory with 5,000 workers faced a unique challenge: ambient cotton dust in the factory air was being drawn into the kitchen ventilation, rapidly clogging standard filters. The Heavy-duty Series units were specified with an additional pre-filter stage (washable synthetic media, MERV 8) that captures ambient dust before it reaches the ESP cells. Pre-filter cleaning is a 10-minute daily job for kitchen staff.
- Mining site camp kitchen (Australia): A remote mining camp in Western Australia serving 500 FIFO workers operates 24/7 in an environment where ambient temperatures exceed 40°C and red dust is ever-present. The Heavy-duty Series with heavy-gauge pre-filters handles both the cooking emissions and ambient dust load. The units are housed in a fully enclosed plant room with filtered intake air — a lesson learned after the first installation without intake filtration failed within 3 months of commissioning.
